Definitions
- the disclosure relates to an assistance control system, and more particularly to an assistance control system adapted to facilitate operation of a cycle.
- a cycle e.g., a bicycle
- an assistance module e.g., an electric bicycle
- the assistance module determines, based on the pedaling force sensed by the torque sensor, a level of auxiliary propulsion power to be provided by the assistance module for assisting propulsion of the cycle so as to reduce the force required to pedal the cycle.
- the level of auxiliary propulsion power provided is positively correlated to the pedaling force, so such control scheme is not so convenient to the cyclist, especially when the cyclist is too tired to pedal.
- an object of the disclosure is to provide an assistance control system adapted to facilitate operation of a cycle that can alleviate at least one of the drawbacks of the prior art.
- the cycle includes a cycle body, and an assistance module that is controlled to output an assistive torque for driving movement of the cycle body.
- the assistance control system includes a sensor mounted on the cycle body, and a controller communicable with the sensor and the assistance module .
- the sensor is configured to sense operation of the cycle body so as to output a sense signal indicative of a state of usage of the cycle body.
- the controller is configured to switch between a boost mode and a deboost mode based on the sense signal. In the boost mode, the controller outputs a control signal to the assistance module so as to control the assistance module to enhance the assistive torque. In the deboost mode, the controller outputs the control signal to the assistance module so as to control the assistance module to decrease the assistive torque.
- the cycle 9 includes a cycle body 91, and an assistance module 92 that is controlled to output an assistive torque for driving movement of the cycle body 91.
- provision of the assistive torque by the assistance module 92 is implemented by a motor-drive mechanism. Since the motor-drive mechanism has been well known to one skilled in the relevant art, detailed explanation of the same is omitted herein for the sake of brevity.
- the cycle body 91 includes two pedals 911, two brake-levers 913 (only a single brake-lever 913 is shown in Figures 1 and 3 ), a bottom bracket spindle 914, and a crankset 912 that is co-rotatably coupled to the bottom bracket spindle 914.
- the pedals 911 are rotatably mounted to the crankset 912.
- One of the bottom bracket spindle 914 and the crankset 912 i.e., either the bottom bracket spindle 914 or the crankset 912 is driven to rotate by the assistance module 92 with the assistive torque .
- Said one of the bottom bracket spindle 914 and the crankset 912 is rotatable in a forward direction (R1) for propelling the cycle 9 to move forward, and also in a backward direction (R2) that is reverse to the forward direction (R1).
- the assistance control system includes a first sensor 2, two second sensors 3 (only a single second sensor 3 is shown in Figures 1 and 3 ), and a controller 4.
- the first sensor 2 is mounted on the cycle body 91.
- the first sensor 2 is configured to sense operation of the cycle body 91 so as to output a first sense signal indicative of a state of usage of the cycle body 91.
- the first sensor 2 is to be mounted on one of the bottom bracket spindle 914 and the crankset 912, and is configured to sense movement of said one of the bottom bracket spindle 914 and the crankset 912.
- the first sense signal indicates a state of movement of said one of the bottom bracket spindle 914 and the crankset 912.
- the state of movement of said one of the bottom bracket spindle 914 and the crankset 912 may be a direction of rotation or a degree of rotation angle.
- the first sensor 2 may be an angular position sensor or a rotary position sensor, but implementation of the first sensor 2 is not limited to the disclosure herein and may vary in other embodiments .
- the second sensors 3 are respectively mounted on the brake-levers 913.
- Each of the second sensors 3 is configured to sense operation of the respective one of the brake-levers 913 and to output a second sense signal based on result of the sensing, wherein the second sense signal is indicative of a state of usage of the cycle body 91.
- the second sense signal indicates that the respective one of the brake-levers 913 is in a pull condition (i.e., is being pulled) .
- the brake-lever 913 in the pull condition is illustrated with dash-dotted lines in Figure 2 .
- each of the second sensors 3 is an electronic switch, but implementation of the second sensors 3 is not limited to the disclosure herein and may vary in other embodiments.
- the controller 4 is communicable with the first sensor 2, the second sensors 3 and the assistance module 92.
- the controller 4 is configured to output a control signal to the assistance module 92 after receiving at least one of the first sense signal and the second sense signals.
- the aforementioned communication is conducted over a wired connection in this embodiment, but may be implemented by wireless transmission in other embodiments.
- the controller 4 in this embodiment is configured to switch between a boost mode, a deboost mode and a stop mode based on the first sense signal, and to switch to an awaken mode based on the second sense signal.
- the controller 4 is configured to switch to the awaken mode when it is determined based on the second sense signal that the corresponding one of the brake-levers 913 has been pulled for a predefined waken period.
- the predefined waken period is two seconds, but is not limited thereto.
- the controller 4 outputs the control signal to control the assistance module 92 to be powered on.
- the controller 4 is further configured to switch to one of the boost mode and the deboost mode when it is determined based on the first sense signal that rotation direction of said one of the bottom bracket spindle 914 and the crankset 912 has been repeatedly transitioned between the forward direction (R1) and the backward direction (R2) for a predefined number of times within a predefined sense period. Note that one transition in either way (from the forward direction (R1) to the backward direction (R2), or from the backward direction (R2) to the forward direction (R1)) is counted as one time. In this embodiment, the predefined number of times is three, and the predefined sense period is three seconds, but these parameters are not limited to examples given in this disclosure.
- the controller 4 is configured to switch to the boost mode when it is determined based on the first sense signal that rotation direction of said one of the bottom bracket spindle 914 and the crankset 912 has been repeatedly and sequentially transitioned from the forward direction (R1) to the backward direction (R2) for the predefined number of times within the predefined sense period while said one of the bottom bracket spindle 914 and the crankset 912 remains in a position (or orientation) that is within a preset angular range.
- the controller 4 outputs the control signal to the assistance module 92 so as to control the assistance module 92 to increase the assistive torque.
- the preset angular range is 45° ⁇ 35° for a right crankarm of the crankset 912, where 0° represents an upward direction (i.e., upright orientation of the right crankarm) and 90° represents a forward direction of the cycle 9 (see Figure 1 ) (i.e., horizontal and forward orientation of the right crankarm).
- the preset angular range is not limited to the example given herein and may vary in other embodiments.
- the controller 4 is configured to switch to the deboost mode when it is determined based on the first sense signal that rotation direction of said one of the bottom bracket spindle 914 and the crankset 912 has been repeatedly and sequentially transitioned from the backward direction (R2) to the forward direction (R1) for the predefined number of times within the predefined sense period while said one of the bottom bracket spindle 914 and the crankset 912 remains in a position (or orientation) that is within another preset angular range different from the preset angular range.
- the controller 4 outputs the control signal to the assistance module 92 so as to control the assistance module 92 to decrease the assistive torque.
- said another preset angular range is 45° ⁇ 35° for a left crankarm of the crankset 912 (see Figure 3 ) .
- said another preset angular range is not limited to the above example and may vary in other embodiments.
- the controller 4 is configured to switch to the stop mode when it is determined based on the first sense signal that said one of the bottom bracket spindle 914 and the crankset 912 has been continuously rotating in the backward direction (R2) for a preset number of turns .
- the controller 4 outputs the control signal to control the assistance module 92 to be powered off .
- the preset number of turns is two in this embodiment, but is not limited thereto in other embodiments. It should be noted that switching to the stop mode is permitted only when the controller 4 has switched to the awaken mode and the assistance module 92 has been powered on.
- mode switching of the controller 4 may be implemented to be triggered based on an arbitrary combination of the first sense signal and the second sense signals.
- the controller 4 is triggered to control the assistance module 92 to provide a first predetermined assistive torque.
- the controller 4 is triggered to control the assistance module 92 to provide a second predetermined assistive torque. Consequently, operations of the cycle 9 with the assistance module 92 may be performed in a way that is directly controllable by the user where the user is given active control over the assistive torque provided by the assistance module 92.
- mode switching of the controller 4 are not ordinary actions required for riding the cycle 9, so unintentional triggering of mode switching is unlikely. However, mode switching of the controller 4 may be triggered in other ways, and the disclosure herein should not be taken as limitations in this respect.
- the assistance control system utilizes the first sensor 2 and/or the second sensors 3 to sense operation of the cycle body 91 so as to output the first sense signal and/or the second sense signal indicative of the state of usage of the cycle body 91. Based on the first sense signal and/or one or both of the second sense signals, the controller 4 switches to one of the boost mode, the deboost mode, the awaken mode and the stop mode, and controls the assistance module 92 to adjust the assistive torque, correspondingly.
- Such control scheme may be easily performed by the cyclist, and facilitates operations of the cycle 9.
- installation of the assistance control system according to the disclosure does not occupy much space.
